romena.

To all elif/mln it may Concern Beit known that l, VVUJLIA'AI D, BARBER, a citizen oi the VUnited States. and resident `ot Chicago, in the county of Cook and State of illinois. have invented a certain new and useful Improvement in a Combined Crib and lntake, of which the following is a deacription, reference being had to thevae- 'conipanying drawingsf which lorm a part'` ot my speeilication. i

My invention relates to a water intake and crib for use in connection with the water- `supply of a municipality, adapted to be 'built or set in the body7 of water, trom which .the simply is had, at a distance from the shore iine whereby the water supplied by gravity to the pumping station or stat-ions on shore.

The invention has for its object the provision of a crib provided with radially arA ranged intakes or pipes intended to be snbmerged and extend to a considerable dis tance trom the crib So to increase the area o'lE supply and thereby reduce the suetion etl'ect heretofore encountered at the intake ports of cribs as previously c mstructiial- Another object being to provide ay crib wherein the.. intake-shaft which leads to the shore 0r pumping; stations will have direct eommi'lnieation with the well ot the crib, thereby eliminating the usual intake which heretofore formed an extension ot the shaft rising' into the well where it has been fitted with suitable slniee gates, so that repair ot the gates and screens would permit the 't'oreign matter'to drop into the well or intakesha'lit'. In the employment ot my improved eonstruction. however, the intake ports of the crib are so formed that the gates and sert-ens are arranged to the outside of the well ot' the crib whore any repair ot the gates or cleaningr of the screens will be to the outside ot' the well and within a gallery or sha'tt wit-h which my improved crib-is provided. thus insuring a purer water supply; passing' into the intake-.shalt leading' to tine shore or pompino station.

'l further objert'. il my unfention is the provision of a crib having' intalw-piyawl or cirudtiits so constructed that water ,will be prtwented trom directlypassing' into the 1ntake endsv of the p1 'lemon' orifices. but be ingtoward the bottom ot the lake or other Specification of Letters Patent.

la ke, thus eliminating the difficulties heretot'ore encountered through sudden changes in velocity and direeton of flow7 cross currents, ctr.: the construction beingsueh that the inta ke ends or ports will not become obstructed by ice, etc., and, therefore, overcoming the great dillieulties heretofore Caused by anchor ice.

it t'urther object ot' my invention is to provide a crib construction whereinr it is made possible to thaw any ice that might vt'orm or become 4lodged at. the intake ends of the intake pipes or conduits; the invention possessing' other advantages inherent. .in the. eoiistruction7 which will, be readily appar ent troni the following' detailed deseription. i

ln the exemplitieation offaiy invention as illustrated in the daaw`i gsr the crib, 'is com'- posed of an outer steelor metallicA "shellA l2 and an inner orcencentrie shell lgyjmaintainedinproper relative positionebythe radially extending' partitions l-ll. ot which any suitable number mayi be employed; and the apatcs bctween the diffeient' partitions l-l are provided with botten sli, moreelearly lshown in Fig'. pre'terali. .slt-cet metal and properly secured to the shells` l2 andlh :is well as to the adjacent partitions lll.- 'lhe bottoms l5 are preterably secured a, dielance within the shells 'l2 and i8 so as to lea ve the ends ot' the shells 'l2 and i3 to extend somewhat below the bottoms l5, as clearlyT shown at l2 and l2" ,y I in Fig. 2. The bottoms 15 may be formed as just described, that is, a separate bottom for each vof the compartments formed by adjacent partitions 14 and the concentric shells 412 and 13, or a single annular plate may be secured beneath the bottoms vof the partitions 14 so as to form water-tight compart` ments; the partitions, of course, need not extend to the bottom edges 12'3L and 13a of shells lo 12 and 13 respectively. The shells 12 and 13 may,y of course, bemade of any suitable size, as for example,`the outer shell maybe 100 feet and the inner'shell 50 feet in diameter so as to rovide an annular space of 15 considerable s1ze between them, which annular space, as previously described, is divided into a'series of Water-'tightl compart-g ments by the radially extendi partititions .14', and bottom or bottoms 1f(V By securing the bottom or bottoms lfwithin the `shells 12 and 13 at a distance removed from the lower edges thereof, a cutting edge is provided which enables the shells to cut or press themselves into the clay bottom of the lake or body `of Water after the crib hasbeen settled into place. f At a point preferably immediately above the bottom or bottoms 15, the shells 12.'and 13 'are provided -with openings or ports, 39 preferably in an alined position intermediatc of the partitions 14, as more clearly shown in Fig. 1. The ports or openings in the outer shell are surroundedvby flanges 16, secured to the outer shell in any suitable manner, the flan es being intended tov re ceive the flange ends of vsuitable intake pipes 117, which .areprovided with orifices` or intakes 18, prefexiablyrplaced and sunken at a. considerable-distance from the crib 40 itself. l

In the preferred form of my invention, the intake. ports or conduits 19 are bifurcated or provided with ramifications 19'L and 19h, as more clearly shown in Fig. 1'; and, therefore, the outer shell 12 is provided with twoflanges 16 in each compartment intermediate of adjacently placed partitions 14; the bifurcations of the intake ports being preferablyv so arranged that the intake pipes or conduits connected thereto will be arranged radially and the intake area greatly spread, so that the water Within this area Vwill not 'be subjected to such action as would tend to quick or sudden changes. The inner shell 13 also has its ports surroundedl by suitable flanges as shown vat 20, to Which suitable steel frames and fittings may be secured so as to 1receive sluice gates 21, which latter may be of any suitable construction and op- V erable in a vertical direction.

The frames secured to the flanges 20 of the inner shell 13 are preferably also constructed so as to accommodate or receive suitable y screens, arranged forward of the sluice gates, as more clearly shown at 22, see Figs.

-1, 2, 7, and

being located withinthe respective compart 8; the sluice gatesand screens ments formed intermediate of the Ainner shell 13 and outer shell 12 and partitions 1 4, and operable in ,shafts built`within the compartments.' It is apparent therefore that with my improved Aconstruction the sluice gates and screens are located outside ofthe lwell indicated at 23, formedA Within the inner shell 13, thereby insuring va purer water supply than with constructions at present in use. The screens 22, which like the sluice gates'21, are preferably arranged `to move vertically in the vrespective shafts 25 by means of a well known construction of guide-ways; the'screens and sluice gates being of any Well known constructions. In theexemplification, I have chosen to illustrate a screen- (which may be wire mesh or perforated sheet metal), thc main or body portion whereof is somewhat, in the nature of a 'basket with the one Wall, preferably .the one adjacent to the sluice gate, being extended vertically as very. clearly shown in "Figs 2li-nd 7 solas to normally extend across the entire orifice or inlet; the vertically disposed side or portion of the lscreen prevent'- ing `solids or foreign matter passing through the inlet when the sluice gate -is open; while thehorizontally disposed or basket portiony Will--facilitate-the solids or foreign matter lodging within the bottom of the respective shafts-25 being brought or drawn upward,

vas. is clearly apparent,by means of a cable or othermechanismv being secured to the mainportion thereof. It is understood, that the essential function of the screen is to revent the passage of Vsolids through the inlets when the sluice gateis open, so that whatever the construction of or body however,

the screen may be, it should be provided portion comwitha 'vertically disposed formed by the pletely coveringpthe opening sluice gates.

In practice, the steel shells 12 and 13 together with the ra ially extendingpartitions 14 and the bo tom or bottoms 15 are built before the steel crib is itowed out to the point Where it is to be located; the shells having ouslv described, which h'ave also been provided with the flanges heretofore referredA to; and, if desired, the intake conduits 19 may also be built into place before the crib is towed out. The openings orports in both the interior and outer shells are properly capped or closed so that,a series of watertight compartments will be provided intermediate of the inner and outer shells which will maintain the construction afloat until the point where the crib is to. be located has been reached.

It is evident from the construction Just described that the opening of the respective ports by the removal of the cap or plug been provided with the ports previ-- by a iianged position.

. inner and outer shells and www *iwill permit the different compartments to l"till with water in come firmly embedded in the bottom of theA lake or other body of water, the bottom of each compartment is preferably pierced pipe 2li, see Fig. :4, whereby the water located beneath the bottom ot the compartments and intermediate of the depending` edges of the shells l2 aud 18 may be pumped or drawn from under each compartment and permit the depending,` edges of the concentric shells to out into the clay or bottom until the bottom l5 of the compartments rests upon the clay bottom of the body of water; the entire structure being thus firmly drawn or settled into its final The shells 12 and 18, it will be understood, are of such width vertically that they will extend a suiiicient distance above the surface of the water when in final settled position; After the shell construction has thus become Jdually settled into place,

which is, ot course, at the point Where the intake shaft, which leads to the shore or` pumping station, terminates, the various latentig'ht compartments 'forined by thc the radially disposed partitions, are then pumped out, preferably one at a time, the compartments are then filled in with suitable material, as for example adjoining the inner and outer shells a wall of concrete ol suilicient thickness built so as to provide a shaft in each compartment, extending' from the intake ports up to the upper edge of the shells or top of the crib, as vvery clearly indicated in Fig. 2; concrete being):r preferably employed around the various port-s and shafts Vand adjacent the shells, while the space intermediate ot the concrete walls Ithus formed niay be filled with broken stone, clay and sand lhorougijhly puddled and tamped up to a point which. is to constitute the floor of the crib, namely a proper distance above the water level. The sluice gates, screens7 and operating mechanism it'or the gates and screens are then built in each shaft.

T-ie rarious compartments or pockets having; bren finished in the manner just decr the space within the inner shell i3 pumped out and a well 28 built preferably et concrete as shown `in preferably with sloping or con- A walls, as shown in Fig'. 2. terminatiupin an opening' at the top, inclosed by a suitable supra-.slructure, whereby access and proper obstrrationsy may constantly be had; thc upper part ol the well beine' lined with suitable lig-ht reflecting material, if desired, The lower part. of the well, ot course, is pro- `vided with the ports as shown at 2G in Fig'. 2, in alincinent with the intake ports `or con- -tom of the lake, or

duits 19;'and the well terminates in or coininunicaes al' its bottom with the intakeshait 2T, whereby the water is conveyed or prrmitted to Yf'low from the well to the pumping` station on shore. I Aliter the well has been completed, the in; take pipes or conduits 17, which are preferably .laid in trenches excavated in the botother body` of water, are then secured to the hanged couplings 16 .secured about the ports of outer shell l2, as very clearly'shown in Fig. rl`he intake pipes,'of which I illustrate two to cach port l), may be madeto extend different distances from the crib as indicated for eX- ample in the diagrammatic views 3 and el. rifhe outer or inlet ends of the intake 1'( are presented upwardly as very clearly shown at 18 in Fig. 5 5 the intake ends being preferably provided with an anchor or support as indicated at 27, see Fig. 5, of a su1table construction whereby the inlet ends 18 are maintained in proper elevated position. The orifices ot the intake ends 18 are pro- Ivided with hoods, as indicated at 28, preferably of steel and cone shaped as indicated in Fig. 5, so that the water will not How into the intake ends 18 from a point .immediately above, but be compelled to flow lnto the intake pipes from a point below the plane of the orifices of the intake ends 18, as is readily apparent from the construction shown in Fig. 5.

ln order that large particles of foreign substance cannot enter the intake pipes, I prefer to support the hoods 2S by a grating as indicated at 29 which may be secured to the hood and the intake ends 18 in any suitable manner. The lower surfacevor insides of the hoods may be lined with zinc or brass, and the bars or grating 29 also be of polished brass, or other suitable metal, to which ice will not adhere; As the hoods 28 may be oi' considerable diameter, it is evident that the area of inflow to each intake conduit or pipe will be distributed to a large area of the lake bottom.

in practice, it may be deemed advisable' to surround the intake ends y18 of the intake conduits with concrete; and the intake pipes alv the point where they are securedlto the outer shell of the' crib may also be pilotected bv a sufficient quantity ot' broken stone, as illustrated for example in Fig. 2, so 'as not to have the intake pipes subjected `to the effect oi ice jams and other disturbances. With the hood construction at the intake ends ot' the intake pipes, any heavy material that may be dropped into the water from the surface would be deflected to one side ot' the intake ends by the hood, while lighter materials would be loss apt to pass into the intake ends because oi the manner in which thc water is compelled to tiow into the in take pipes.

pipesr hood; the pipe communicating with a suitintake shaft as clearly shaft 25 leading from lable hot water tank located on the crib or inthe superstructure thereon. Should such a .condition arise, the intake gate ofthe particular intake conduit andhot water allowed to flow through the pipe 30 by gravity, or otherwise,`and be discharged within the hood at the intake end, whereby the anchor and the intake pipe orconduit again restored to operative condition.

The upper ends of the shafts 25 may terminate in a suitable gallery or galleries as indicated for example at 31, see Fig. 2, which may completely surround the well 23, so that access to all of the shafts 25 vmay be readily had; the gallery or galleries which 'communicate with the shafts 25 being provided with any suitable mechanism whereby the respective gates and screens may be independently operated; the shafts 25 being provided with suitable guides or slide-ways for the gates and screens.

In addition to the gallery indicated at 31 in Fig. 2,'cne or'more passages, as indicated at 32, may be provided, extending from the gallery to the upper part or restrictedv part of the well and above the water line thereof,

so that access to the well may be had from the vgallery 31,- in which the gate and screen operating mechanism is preferably located. The well 23 is preferably provided with converving walls above the inlet ports therein,

'while the bottom? of the well opens into the construction being such that cross and other currents of Water will be diminished, and

any material that 'mayimproperlyenter the 4wel-l will be permitted to rise to the Atop where itcan be readily removed from the reduced or confined area' at the well top.

The operating shafts 25 may be constructed of metal conduits of sufficient diameter and construction to permit of vertical movement of the sluice gates as well as the fish screens located adjacent thereto, built into place within the shells before the latter are towed to position; and the pipes 30 for conveying hot water or'btlier ice thawing solution to the hooded inlet ends of the intake "pes may be arranged within' each ofthe vconduits-or pipes 17, as illustrated in the drawings with the inner 30 extendingupward within the respective the respective conduit. I'have shown and described what I believe to thesimplest and bst form of my invention, which, however, may permit ofV would then be closedv water-tight inclosure ice would soon be thawed 'a pair shown in Fig. 2, the
